   Hint

   Think about how impurities might affect concrete.

2. 2.

   Name one organic impurity that could be present in water.

   Hint

   Recall common things found in natural water bodies.

3. 3.

   What is the primary purpose of chemical analysis of water?

   • To determine pH
   • To identify harmful impurities
   • To measure temperature

   Hint

   Think about the risks involved in using contaminated water.

4. 4.

   True or False: High chloride levels can strengthen the concrete mix.

   • True
   • False

   Hint

   Consider the impact of corrosion.

5. 5.

   You have a water sample with high chloride levels. Propose a solution to make it suitable for construction.

   Hint

   What processes are common in water treatment?

6. 6.

   Describe a scenario where water high in organic impurities was used and the consequences faced by the construction team.

   Hint

   Think about the effects on strength and durability.
